Coordinating the use of independent radio receivers associated with multiple different transmitters

ABSTRACT

A computer-implemented method includes discovering, by a client device, an available host computing device implementing a radio receiver, wherein the host computing device is discovered from a decentralized shared database and the radio receiver receives radio signals from multiple different transmitters; establishing, by the client device, a relationship with the host computing device based on discovering the host computing device from the decentralized shared database; receiving, by the client device, application data from the host computing device based on establishing the relationship, wherein the application data is associated with radio signals received by the radio receiver from the multiple different transmitters; and storing, outputting, or displaying, by the client device, the application data.

BACKGROUND

The present invention generally relates to coordinating the use of unrelated radio receivers and, more particularly, to coordinating the use of unrelated radio receivers that receive radio signals from multiple different transmitters.

Radio receivers, such as software defined radios (SDRs) are radio communication systems in which components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by software on a personal computer or embedded system. A basic SDR system may include a computer device (e.g., a personal computer, miniature computer, mobile device, etc.) equipped with a sound card, or other analog-to-digital converter, preceded by some form of radio frequency (RF) front end. In an SDR system, significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware (electronic circuits). Such a design produces a radio which can receive and transmit widely different radio protocols or frequencies (sometimes referred to as waveforms) based solely on the software used.

SDR receivers are used in applications in which a wide variety of changing radio protocols and frequencies are required in real time. SDR receivers are often individually owned and operated, and thus, coordinating the use of multiple different SDR receivers for various applications is complex, if at all possible.

DETAILED DESCRIPTION

The present invention generally relates to coordinating the use of unrelated radio receivers and, more particularly, to coordinating the use of unrelated radio receivers that receive radio signals from multiple different transmitters. As described herein, aspects of the present invention may include systems and/or methods to discover, negotiate, and contract with radio receivers in order to coordinate the use of unrelated radio receivers that receive radio signals from multiple different transmitters. In embodiments, the radio receivers may be implemented by host computing devices (e.g., portable computing devices, miniature computing devices, mobile computing devices, etc.). For example, a host computing device may include an integrated or external peripheral radio receiver. The radio receiver may include an SDR receiver and/or other type of radio receiver.

In embodiments, independent and unrelated host computing devices each implementing independent and unrelated radio receivers may provide information indicating their respective availabilities to be contracted with and/or used for various applications. As described herein, a client device may contract with one or more host computing devices in to order utilize the radio receivers of the host computing devices in which the radio receivers receive signals transmitted by multiple different transmitters. For example, a client device may contract with one or more host computing devices in order to implement an application using the radio receivers (e.g., an aircraft location identification application, a signal strength waterfall generation application, and/or other application based on radio signals received from multiple different transmitters). Additionally, or alternatively, one or more host computing devices may contract with a client device.

As described herein, a blockchain, peer-to-peer network, and/or similar technique may be used to provide host computing device information (e.g., information identifying the availability of host computing devices and their respective radio receivers to be contracted). That is, the host computing device information may be decentralized, and the blockchain may be used as a decentralized shared database of host computing device information. A client device may discover a host computing device from the blockchain in order to establish a contracting relationship with the host computing device. Advantageously, the use of scattered, unrelated, and independent radio receivers can be coordinated for various applications, such as radio spectrum analysis (e.g., signal strength waterfall generation), flight tracking, or the like.

Aspects of the present invention provide a technical solution to the technical problem of coordinating the use of scattered, unrelated, and independent radio receivers. For example, aspects of the present invention include a system and/or method to provide consolidated host computing device information (e.g., via a blockchain) which identifies radio receivers associated with a single transmitter that can contracted and used for a particular application (e.g., radio spectrum analysis, aircraft location identification, etc.). Further, aspects of the present invention provide a technical solution to the technical problem of producing a signal strength waterfall. For example, aspects of the present invention include a system and/or method to receive signal strength information from various unrelated radio receivers that receive radio signals from multiple different transmitters at various frequencies. Aspects of the present invention generate a waterfall based on the received signal strength information. Further, aspects of the present invention provide a technical solution to the technical problem locating aircraft during flights. For example, aspects of the present invention include a system and/or method to receive aircraft location information for multiple different aircraft via radio signals received from respective aircraft location information transmitters implemented within the aircrafts.

The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 1, a schematic of an example of a cloud computing node is shown. Cloud computing node 10 is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node 10 is capable of being implemented and/or performing any of the functionality set forth hereinabove.

In cloud computing node 10 there is a computer system/server 12, which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server 12 include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like.

Computer system/server 12 may be described in the general context of computer system executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server 12 may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

As shown in FIG. 1, computer system/server 12 in cloud computing node 10 is shown in the form of a general-purpose computing device. The components of computer system/server 12 may include, but are not limited to, one or more processors or processing units 16, a system memory 28, and a bus 18 that couples various system components including system memory 28 to processor 16.

Bus 18 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.

Computer system/server 12 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server 12, and it includes both volatile and non-volatile media, removable and non-removable media.

System memory 28 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 30 and/or cache memory 32. Computer system/server 12 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 34 can be provided for reading from and writing to a nonremovable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 18 by one or more data media interfaces. As will be further depicted and described below, memory 28 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.

Program/utility 40, having a set (at least one) of program modules 42, may be stored in memory 28 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules 42 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.

Computer system/server 12 may also communicate with one or more external devices 14 such as a keyboard, a pointing device, a display 24, etc.; one or more devices that enable a user to interact with computer system/server 12; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server 12 to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces 22. Still yet, computer system/server 12 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 20. As depicted, network adapter 20 communicates with the other components of computer system/server 12 via bus 18. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server 12. Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.

Referring now to FIG. 2, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 comprises one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 2 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 3, a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 2) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 3 are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided:

Hardware and software layer 60 includes hardware and software components. Examples of hardware components include: mainframes 61; RISC (Reduced Instruction Set Computer) architecture based servers 62; servers 63; blade servers 64; storage devices 65; and networks and networking components 66. In some embodiments, software components include network application server software 67 and database software 68.

Virtualization layer 70 provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers 71; virtual storage 72; virtual networks 73, including virtual private networks; virtual applications and operating systems 74; and virtual clients 75.

In one example, management layer 80 may provide the functions described below. Resource provisioning 81 provides dynamic procurement of computing resources and other resources that are utilized to perform tasks within the cloud computing environment. Metering and Pricing 82 provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may comprise application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User portal 83 provides access to the cloud computing environment for consumers and system administrators. Service level management 84 provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) planning and fulfillment 85 provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA.

Workloads layer 90 provides examples of functionality for which the cloud computing environment may be utilized. Examples of workloads and functions which may be provided from this layer include: mapping and navigation 91; software development and lifecycle management 92; virtual classroom education delivery 93; data analytics processing 94; transaction processing 95; and radio receiver application processing 96.

Referring back to FIG. 1, the program/utility 40 may include one or more program modules 42 that generally carry out the functions and/or methodologies of embodiments of the invention as described herein including functionality of the radio receiver application processing 96 of FIG. 3. Specifically, the program modules 42 may discover host computing devices, request access to use radio receivers on the host computing devices (in which the radio receivers receive radio signals from multiple different transmitters), and receive application data related to an application that uses the radio receivers of the host computing devices. Other functionalities of the program modules 42 are described further herein such that the program modules 42 are not limited to the functions described above. Moreover, it is noted that some of the modules 42 can be implemented within the infrastructure shown in FIGS. 1-3. For example, the modules 42 may be representative of a client device and/or a host computing device as shown in FIG. 4.

FIG. 4 shows an overview of an example implementation in accordance with aspects of the present invention. As shown in FIG. 4, environment 400 may include a client device 210, a host computing device 215, a radio receiver 220, transmitters 225-1 and 225-2, a blockchain network 230, and a network 240. Client device 210 and host computing device 215 may include one or more of the components of computing system/server 12 of FIG. 1, such as one or more program modules 42.

As shown in FIG. 4, the host computing device 215 may implement a radio receiver 220 that receives radio signals from multiple transmitters (e.g., transmitters 225-1 and 225-2). The client device 210 and the host computing device 215 may communicate with a blockchain network 230. The blockchain network 230 may include a peer-to-peer network via which a blockchain (e.g., a shared database) is exchanged and synchronized between participants of the blockchain network 230. For example, the participants of the blockchain network 230 may include any type of computing device that is capable of communicating via a computing network. In the example of FIG. 4, the client device 210 and the host computing device 215 may be participants of the blockchain network 230, and thus, the client device 210 and the host computing device 215 may each store or access the same blockchain. As described herein, the blockchain may include host computing device participation information in which host computing devices that are available for contracting are identified in the blockchain.

At step 1.1, the client device 210 may discover the host computing device 215 from the blockchain. For example, the client device 210 may filter the blockchain to identify host computing devices that meet particular criteria (e.g., contracting/pricing criteria, application compatibility criteria, radio operating frequency criteria, geographic location criteria, an identifier of a transmitter from which radio signals are received, etc.). In embodiments, the client device 210 may filter the blockchain based on real-time user input of filtering criteria. Additionally, or alternatively, the client device 210 may automatically filter the blockchain based on preconfigured criteria (e.g., each time radio receiver services are needed from a host computing device).

At step 1.2, the client device 210 may provide an application code for execution on the host computing device 215. For example, the client device 210 may provide the application code via a network 240 (e.g., an external network such as the Internet, a virtual private network (VPN), cellular network, etc.). Alternatively, the client device 210 may provide an instruction for the host computing device 215 to obtain the application code from another source. As described herein, the application code includes instructions for the host computing device 215 to process and/or provide data relating to radio signals received by its radio receiver 220 from the transmitter 225. For example, the application code may relate to a signal strength waterfall generation application, a flight locator application, or the like.

In embodiments, the host computing device 215 may receive the application code, and may validate and/or authenticate the application code (e.g., to ensure that the application code is received from an authorized device and does not include malicious and/or hazardous code). For example, the host computing device 215 may authenticate the code using any combination of authentication, encryption, decryption, and/or other techniques.

After receiving and authenticating the application code, at step 1.3, the host computing device 215 may execute the application code, and step 1.4, the host computing device 215 may provide application data to the client device 210. The application data may include data relating to the executed application. As an example, the host computing device 215 may execute the application code to provide the client device 210 with application data including information identifying the signal strength of signals received from transmitters 225-1 and 225-2. For example, the host computing device 215 may execute the application code to tune the radio receiver 220 to a particular frequency at which the transmitter 225-1 is transmitting, receive the radio signals transmitted by the transmitter 225-1, and provide the application data. The host computing device 215 may execute the application code to also tune the radio receiver 220 to a particular frequency at which the transmitter 225-2 is transmitting, receive the radio signals transmitted by the transmitter 225-2, and provide the application data. The client device 210 may use the application data to generate a signal strength waterfall (e.g., by consolidating signal strength information for signals received at different frequencies from different transmitters).

As another example described herein, multiple different host computing devices 215 may be contracted by the client device 210 to receive data relating to radio signals received from different transmitters. In this way, information from independent and unrelated radio receivers that each reactive radio signals from different transmitters can be coordinated in a simple and effective manner.

In embodiments, the client device 210 may store, output, or display the application data (step 1.5). For example, the client device 210 may display the application data in the form of a waterfall (e.g., a signal strength waterfall), a chart, a graph, or other format. In embodiments, the application data may include aircraft location information, and the client device 210 may use the application data to generate a map that identifies the location of aircrafts. In embodiments, the client device 210 may output the application data to another device. For example, the client device 210 may be a cloud server that may store the application data for access by an external device.

As described herein, independent and unrelated host computing devices each implementing independent and unrelated radio receivers may provide information indicating their respective availabilities to be contracted with and/or used for various applications. For example, a client device may contract with one or more host computing devices in to order utilize the radio receivers of the host computing devices in which the radio receivers receive signals transmitted by multiple different transmitters. In embodiments, a contracted host computing device may obtain and execute an application or a code container in order to provide the client device with a service relating to the use of the radio receiver. As an example, contracted host computing devices may execute an application which directs the contracted host computing devices to output information regarding respective signal strengths for received signals transmitted by multiple different transmitters within a particular geographic area. The client device may use the signal strength information to generate a signal strength waterfall identifying the signal strength of received transmitter signals at various frequencies.

In embodiments, multiple contracted host computing devices may each execute an application that directs each host computing devices to provide data relating to radio signals received from different transmitters (e.g., aircraft location information). As an illustrative example, a host computing device may receive radio signals from an automatic dependent surveillance broadcast (ADS-B) transmitter implemented in an aircraft (e.g., when the host computing device is within communications range of the ADS-B transmitter). The ADS-B transmitter may provide radio signals that identify the location of the aircraft. Multiple host computing devices may each receive radio signals from multiple different ADS-B transmitters, and may output data relating to the received signals (e.g., the location of aircrafts) to a client device. The client device may display a map with the locations of the aircrafts.

As described herein, a blockchain, peer-to-peer network, and/or similar technique may be used to provide host computing device information (e.g., information identifying the availability of host computing devices and their respective radio receivers to be contracted). That is, the host computing device information may be decentralized, and the blockchain may be a decentralized shared database of host computing device information. The host computing device information may identify the types of radio receivers implemented by the host computing devices, operating frequencies of the radio receivers, applications that the host computing device may implement, etc. A client device may discover a host computing device from the blockchain, and may filter the blockchain to identify host computing devices that meet certain criteria based on a desired application. For example, if the client device is to be used to identify received signal strengths from a particular transmitter within a particular geographic area, the blockchain may be searched and/or filtered to identify host computing devices that implement radio receivers within the particular geographic area and receive signals from a particular transmitter. Further, the provided host computing device information may identify pricing terms, service level agreements, and/or other contracting terms. The client device may be used to filter host computing devices based on the contracting terms. Advantageously, the use of scattered, unrelated, and independent radio receivers can be coordinated for various applications, such as radio spectrum analysis (e.g., signal strength waterfall generation), flight tracking, or the like.

The quantity of devices and/or networks in the environment of FIG. 4 is not limited to what is shown in FIG. 4. In practice, the environments may include additional devices and/or networks; fewer devices and/or networks; different devices and/or networks; or differently arranged devices and/or networks than illustrated in FIG. 4. Further, some elements in the environment of FIG. 4 may be separated into multiple elements, whereas multiple elements may be combined into a single element (e.g., block chain network 230 and network 240 may be a single network). Also, in some implementations, one or more of the devices of the environments may perform one or more functions described as being performed by another one or more of the devices of the environments. Devices of the environments may interconnect via wired connections, wireless connections, or a combination of wired and wireless connections.

FIG. 5 shows an example flowchart for coordinating the use of radio receivers that receive radio signals from multiple different transmitters in accordance with aspects of the present invention. The steps of FIG. 5 may be implemented in the environment of FIG. 4, for example, and are described using reference numbers of elements depicted in FIG. 4. As noted above, the flowchart illustrates the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention.

As shown in FIG. 5, process 500 may include discovering host computing device(s) from a blockchain (step 510). For example, the client device 210 may discover one or more host computing devices 215 from a blockchain (e.g., in a similar manner as described above with respect to step 1.1 and 2.1 of FIG. 4 and FIG. 5, respectively). In embodiments, client device 210 may discover as many host computing devices 215 as needed for a particular application. For example, for certain applications, access to only one host computing device 215 may be needed (e.g., for a waterfall generation application in which a particular host computing device 215 is within communications range of multiple transmitters 225).

Process 500 may also include requesting access to the host computing device (s) that receive radio signals from multiple different transmitters (step 520). For example, the client device 210 may provide a request to access the host computing device(s) 215. In embodiments, the request may include a radio usage proposal that identifies the terms under which the host computing device(s) 215 may be accessed (e.g., pricing terms, service level agreements, applications that the host computing device(s) 215 may execute based on received radio signals, etc.) In embodiments, the host computing device(s) 215 may accept the request, and provide an indication regarding the acceptance to the client device 210.

Process 500 may also include establishing a contracting relationship with the host computing device(s) 215 (step 530). For example, the client device 210 may establish a contracting relationship with the host computing device(s) 215 based on receiving the acceptance of the request (e.g., by establishing a peer-to-peer connection between the client device 210 and the host computing device(s) 215). In embodiments, transaction information may be recorded to a blockchain to facilitate a transaction in connection with establishing the contracting relationship. For example, the client device 210 may write information to the blockchain that effectuates a transfer of funds from an account of the client device 210 to an escrow account. In embodiments, the information may be written to the blockchain on behalf of the client device 210 via a mining service.

Process 500 may also include providing application code (step 540). For example, the client device 210 may provide the application code to the host computing device(s) 215 (e.g., in a similar manner as described above with respect to step 1.2 of FIG. 4). In embodiments, the client device 210 may provide the application code and/or information that the host computing device(s) 215 may use to obtain the application code (e.g., from another source other than the host computing device 215). Process 500 may further include receiving application data (step 550). For example, the client device 210 may receive the application data from the host computing device(s) 215 (e.g., as described above with respect to step 1.4 FIG. 4). In embodiments (e.g., when the application data is received), the client device 210 may write transaction information (e.g., via a mining service) to the blockchain that effectuates a transfer of funds from the escrow account to an account of the host computing device(s) 215.

Process 500 may also include storing, outputting, or displaying the application data (step 560). For example, the client device 210 may store, output, or display the application data (e.g., in a similar manner described above with respect to steps 1.5 of FIG. 4.

FIG. 6 shows an example implementation for coordinating the use of a radio receiver that receives signals from multiple transmitters to generate a signal strength waterfall in accordance with aspects of the present invention. As shown in FIG. 6, a radio receiver 220 may receive radio signals from multiple transmitters (e.g. transmitters 225-1 through 225-N, where N is an integer greater than or equal to 2). In the example of FIG. 6, the client device 210 has contracted with host computing device 215 for receiving signal strength information (e.g., based on the processes described herein). The host computing device 215 may execute application code and provide application data to the client device 210 in which the application data includes signal strength reception information for signals received from transmitters 225-1 through 225-N at different frequencies. Specifically, the application code may direct host computing device 215 to tune to the radio receiver 220 to different frequencies in order to receive radio signals from transmitters 225-1 through 225-N (e.g., in which each of transmitters 225-1 through 225-N transmits signals at different respective frequencies). Further, the application code may direct host computing device 215 to output information regarding the signal reception strength (e.g., the application data) to the client device 210.

The client device 210 may receive the application data, and may generate a signal strength waterfall (as shown interface 600) that identifies the signal strengths for signals transmitted by the transmitters 225-1 through 225-N and received by the radio receiver 220 of the host computing device 215. For example, the signal strength waterfall may identify strengths of the received signals at various frequencies (e.g., in which signals of the various frequencies are transmitted by different transmitters 225). In embodiments, the signal strength waterfall may display different colors, shades, and/or patterns that indicate the received signal strengths. Further, the signal strength waterfall may identify the received signal strengths during a particular time window. In embodiments, interface 600 may include an application selector 605 in which a spectrum analysis application may be selected in order for the signal strength waterfall to be displayed.

FIG. 7 shows an example implementation for coordinating the use of multiple radio receivers that receive signals from multiple different transmitters to generate a flight tracking map in accordance with aspects of the present invention. As shown in FIG. 7, radio receivers 220-1 through 220-N (where N is an integer that is greater than or equal to 2) may receive radio signals from transmitters 225-1 through 225-X (where X is an integer that is greater than or equal to 2). In the example of FIG. 7, the transmitters 225-1 through 225-X may include ADS-B transmitters implemented in respective aircraft. Each transmitter 225 may provide a radio signal that indicates the location of its respective aircraft. Radio receives 220-1 through 220-N may receive the radio signals from the transmitters 225-1 through 225-X. In the example of FIG. 7, the client device 210 contracts with the host computing devices 215-1 through 215-N for receiving flight location data (e.g., based on the processes described herein).

The host computing devices 215-1 through 215-N may execute application code and provide application data to the client device 210 in which the application data includes flight location information for signals received from transmitters 225-1 through 225-X. Specifically, the application code may direct each host computing device 215 to tune to output information regarding the radio signals (e.g., corresponding to flight location information) received by respective radio receivers 220 (e.g., the application data) to the client device 210.

The client device 210 may receive the application data, and may generate a flight tracking map (as shown interface 700) that identifies the location of aircraft based on the radio signals (e.g., ADS-B signals) provide by the transmitters 225-1 through 225-X and received by the radio receivers 220-1 through 220-N of the host computing devices 215-1 through 215-N. For example, the flight tracking map may include icons that represent aircraft on a geographic map. In embodiments, the flight tracking map may be refreshed or updated in real-time as the position of the aircraft changes during flight. For example, the client device 210 may continuously receive application data indicating the position of the aircraft during flight, and may update the flight tracking map with up to date information (e.g., at regular intervals). In embodiments, an icon of an aircraft may be selected via interface 700 in order to obtain detailed information regarding the aircraft (e.g., aircraft information, aircraft position, etc.). In embodiments, interface 700 may include an application selector 705 in which a flight tracking application may be selected in order for the flight tracking map to be displayed.

In the example of FIG. 7 a particular radio receiver, e.g., radio receiver 220-1, may receive radio signals from a single transmitter, e.g., transmitter 225-1, or from multiple transmitters, e.g., transmitters 225-1 through 225-X. The application data may include flight location data from a single host computing device 215 whose radio receiver 220 receives radio signals from multiple different transmitters. e.g., transmitters 225-1 through 225-X. Alternatively, the application data may include flight location data from multiple host computing devices, e.g., host computing devices 215-1 through 215-N whose radio receivers, e.g. radio receives 220-1 through 220-N, receive radio signals from multiple different transmitters, e.g., transmitters 225-1 through 225-X. In embodiments, multiple radio receivers, e.g. radio receives 220-1 through 220-N, may receive radio signals from a single transmitter (e.g., a single ADS-B transmitter), and the application data may include flight location data received by the multiple radio receivers.
